Best of Breed: Meal Replacement Bars, Protein Bars, Energy Bars

There are countless companies producing nutrition bars that can be found virtually anywhere, from gyms to supermarkets and even gas stations and convenience stores.

While nutrition bars may have reached an all-time high in popularity, many people who consume them don’t bother to read the nutritional information to fully understand what they’re eating.

While some bars can be good alternatives to traditional meals, many aren’t. It’s important to know what you’re eating, so here are some guidelines to help you choose the best bar for you.

Read the Label

While the name can lead you to believe the bar inside provides a healthy, low-fat snack packed with energy and nutrients, when you start reading the nutritional content, it soon becomes apparent that not all nutrition bars deliver everything they promise.

Some bars are billed as meal replacements, others are designed to boost energy, some are packed with concentrated amounts of fiber or protein and others are specifically created for pre- or post-workout consumption.

The popularity of nutrition bars has led some companies to produce low-cost alternatives that aren’t much more than bars of muesli glazed with sugar. Such bars provide little actual nutrition, so reading nutritional content information is more than important–it’s absolutely necessary.


The calorie count of nutrition bars can vary greatly.

The average bar is made for people using them for weight management. Weight management doesn’t necessarily mean weight loss. While some people are trying to lose weight by cutting down body fat, others are after more calories and protein in an effort to gain weight, specifically muscle weight.

If weight loss is a part of your fitness goals, it’s important to know how many calories you’re consuming, and that includes the calories in your nutrition bar. And don’t confuse low-fat with low calorie. Many “low-fat” bars pack 200+ calories; that can be more than 10% of the recommended daily caloric intake for the average person.

On the other end of the spectrum are those individuals trying to gain weight who are using bars to add protein and calories in an attempt to boost muscle gain. High quality protein bars can offer more calories along with a balance of protein and carbs to help you power through your workout and assist in muscle synthesis, while low-quality protein bars provide not much more than a bad ratio of calories to proteins and proteins to carbs, along with a heaping dose of sugar.

Watch the Carbs

Along with protein and fat, carbohydrates are an essential macro-nutrient our bodies use mainly for the production of glucose, which our muscles use for energy. Nutrition bars vary greatly in carbohydrate amounts. Some might have 20-30 grams per bar, while others can pack 40 grams or even more. Like any macro-nutrient, more carbohydrates means more calories.

Simple carbs (sugar) can cause a spike in blood sugar and are best avoided. Complex carbs take longer to digest and, as a result, can increase blood sugar levels without causing a spike, thus providing longer lasting energy.

Regardless, one of the first things someone looking to manage his or her weight should look out for is carbs.

High-carbohydrate bars are best consumed pre-workout, as the increase in blood sugar and resulting insulin release can kick-start muscle activity and recovery by pushing nutrients into the cells, providing energy for a more effective workout and also helping recovery.

Recommended Bars

With so many options, choosing the right bar can be a challenge.

The first step is to establish your fitness goals so you can choose the bar or bars that best support them. There are many types of bars available–pre-workout energy boost, meal-replacement, high protein, high fiber….
